Foreign-backed militants in Syria have downed a Syrian government helicopter near the northern city of Aleppo.
The civilian helicopter was carrying exam papers for schoolchildren and all seven people on board, including the deputy head of the Education Ministry were killed.
In a video released by the militants recently, advanced anti-aircraft missiles have been used to bring the helicopter down.
Syrian militants have recently used advanced weaponry supplied to them by the Western and several regional governments in a bid to help them regain their lost ground and forestall the advances of the Syrian army.
The unrest in Syria erupted over two years ago and many people, including large numbers of Syrian soldiers and security personnel, have been killed in the violence.
The Syrian government says the chaos is being orchestrated from outside the country. Last month, President Bashar al-Assad said militants from as many as 29 different countries are operating inside Syria.
A June 26 report by the Wall Street Journal said the US Central Intelligence Agency (CIA) has begun transferring weapons to Jordan in order to arm the Syria militants.
Saudi Arabia’s Foreign Minister Saud al-Faisal said on June 25 that Riyadh believes the al-Qaeda-linked groups in Syria should be armed, but weapons shipments to the Syrian government should be stopped.
Moreover, European Union foreign ministers meeting in Brussels in May reached an agreement to lift the arms embargo on the militants in Syria.
